In males, testosterone is primarily produced by the Leydig cells located in the testes, with smaller quantities also produced by the adrenal glands.
Testosterone is an important androgen, meaning it stimulates the development of male characteristics. According to the provided information:
- Main Source: Testosterone is produced by the gonads, specifically by the Leydig cells in testes in men.
- Secondary Source: Small quantities are also produced by the adrenal glands in both sexes.
Therefore, the testes (specifically the Leydig cells within them) are the primary site of testosterone production in males, supplemented by a minor contribution from the adrenal glands.
Sources of Testosterone Production in Males
Let's break down the key areas responsible for producing this vital hormone in the male body:
| Production Site | Primary vs. Secondary | Notes |
|---|---|---|
| Leydig Cells (in testes) | Primary | Located within the testes; main source. |
| Adrenal Glands | Secondary | Produce small quantities in both males and females. |
These locations work together to maintain the necessary levels of testosterone required for various bodily functions, including the development and maintenance of male reproductive tissues and secondary sexual characteristics.
